What I mostly got out of it is that there are two big ways in which the circle of things with moral worth has shrunk rather than grown throughout history: it shrunk to exclude gods, and it shrunk to exclude dead people.

Leaving aside the dynamics of the Schelling point, did the rest of my reply miss the mark?

I'm not sure what your comment was intended to be, but if it was intended to be a summary of the point I was implicitly trying to make, then it's close enough.
